1.1.3.2.测量方案进场后对设计单位交接的水准点和导线点进行复测，闭合差符合要求后，进行导线点、水准点的加密，加密点必须进行闭合平差，确保加密点的准确，以满足排水管高程，线型控制的精度。

由于井室中桩在施工中要被挖掉，因此在不受施工干扰、易于保护的地方测设施工控制桩，采用延长线法，测设附属构筑物位置控制桩。

施工过程中的测量主要是槽底高程的确定，机械开挖后，采用跟机测量，随挖随测，杜绝超挖现象，确保槽底高程符合设计要求，铺设砂基时，进行复测，发现问题及时处理，使管底高程控制在允许偏差范围内。

每次测量工作开始前，都要进行相邻点的复核测量。

管道中心有井室中心桩来确定，通过控制桩在管道基础上打出边线，确定管道的铺设位置。

Ltd., U.K3. Lifting SchemeThe lifting of the reactor R6300 will be performed with the Kramo climbing jack system introduced from Bidlift Limited, U.K by our company. This system has a maximum liftingcapacity of 2,400t and a maximum lifting height of 140m according to the present configuration of the system we ordered. For this project, only part of the system is needed to perform the lift of the reactor R6300. Therefore, the system is to be used as main lifting gear for the lift of the reactor R6300 and a 400t crawler crane for tailing.The lifting process of the reactor is shown in the following sketches.1. Start Lifting2．Jacks are climbing up while tailing-in crane carries the reactor forwardto vertical position.surface of the foundation.5. The reactor is moved over the foundation by horizontally-moving jacks6. The reactor is lowered in place4. Route for the Equipment Access and Lifting Plan LayoutThe reactor R6300 will be transported to the north side of the foundation along the road on the west side of HDPE/PP plant. After being offloaded, it will be laid as shown in sketch 2 with its top facing west and its end facing east. The plan layout for the lift and the locations of deadman are shown in sketch 3 below.图2Sketch 2Sketch 35. Reactor OffloadingThe offloading of the reactor can be carried out by taking advantage of the hydraulic up-and-down performance of the bogie. The location for laying the reactor shall be leveled and compacted and paved with a 200mm thick layer of gravel. 8 reinforced concrete bearing blocks will be placed before hand for supporting the reactor. The concrete block will be 1.6m×1m×1.2m (L×W×H). These 8 concrete blocks will be arranged in position as shown in sketch 4 prior to the arrival of the reactor to allow access for the bogie to get the midst of the concrete blocks. When the 4 saddles of the reactor are aligned with the concrete blocks, the reactor can be offloaded.Sketch 46．the Lifting System ConfigurationLifting elevation of HDPE reactor R6300 is shown in sketch 5 and sketch 6 below.Sketch 5Sketch 61——Mast Tower2——Lifting Beam3——Climbing Jacks4——Base5——Base Sliding Rail 6—— Swivel 7——Guy Wire System the system components required for the lift of the reactor R6300 are described as follows. 6.1Mast SectionsThe center dimension of the cross section of the mast sections is 2.2m×3m. Altogether 14 sections of 12m long each are needed to build two 84m mast towers.6.2 Lifting BeamThe lifting beam is 18m long with a capacity of 800t.6.3 JacksTwo 400t jacks, each with a power pack.6.4 BaseTwo mast tower bases have a bearing capacity of 1,200t each.6.5 Base Sliding BeamTwo base sliding beams is 15m long each.6.6 SwivelOne set of swivel with a lifting capacity of 800t.6.7 Guy Wire SystemUpper and lower guy wires will be set up.

See sketch 7.图7t G Pa 16063.306.175.27863.306.17=⨯=⨯= One 400t crawler crane will be used for tailing. The operating condition of the crane is: boom length 49m, operating radius 9m. The rated lifting capacity of the crane under thisoperating condition is 204tons, the load percentage is 74.4%, which satisfy the lifting requirement.7.2 Maximum Load of JacksSee sketch 8. During the full process of the lifting operation, the maximum load of the jacks acts on the jacks on the north mast tower, that is the load after the reactor is lifted from the position starting lifting to vertical position. The maximum load P of the jacks is:Sketch 8t Q g G P 2393021185.13)205.278(21185.13)(=⨯+⨯+=+⨯+=where ：G ——reactor weight ，G=278.5t g ——weight of swivel and rigging ，g=20t Q ——weight of the beam ，Q=30t 7.3 Load Force on the GroundSee sketch 9. During the whole process of the lifting operation, the maximum compressivestress the ground under the mast section base bears is: (1) maximum compressive stress N360t on the ground under the inner side of the mast tower; (2) maximum compressive stress 64t on the ground under the outer side of the mast tower.图97.4 Tension Force of Guy Wires and DeadmanSee sketch 10 and Sketch 11. By calculation, the maximum tension force of the guy wires in the direction of north-to-south is 28.2t, their deadman horizontal component of forces is 44t while the vertical component of forces is 33.6. The maximum tension force of the guy wires in the direction of west-to-east is 19.8t, their deadman horizontal component of forces is 31t while the vertical component of forces is 23.7t.The calculation of the tension forces of the guy wires and deadman is attached.Sketch 10Sketch 117.5 the Load Force of the Other ComponentsThe calculation of load forces of the other components will not be described in this scheme since the weight of the reactor R6300 is within the design capacity of the lifting system.8. Selection of Rigging8.1 Main RiggingThe maximum tension force of the main rigging is the same as the weight of the HDPE reactor R6300 278.5t. The rigging is made up by connecting in series 2 pieces of 20m in circumference, φ184mm dia. non-joint wire rope loop to three 400t shackles as shown in sketch 12. The break tensile force of a single φ184mm non-joint wire rope loop is 1,800t and its allowable working load is 300t.8.2 Tail RiggingThe maximum tension force of the tail rigging is 160t. The rigging is made up by connecting in series one 16m long, φ104mm dia. pressed wire sling to a 200t shackle. The sling is used bent double as shown in sketch 13. The break tensile force of a single φ104mm sling is 853t and its allowable working load is 142t. The allowable working load increases to 213t when it is used bent double.Sketch 12 Sketch 139．Procedure for the Erection of the Lifting System & the Lifting of the Reactor 9.1 VesselCheck lifting attachments attached securely per specificationCheck lifting shackles fit lifting attachmentsCheck weight of vessel and location of C of G as expectedCheck for unexpected protruberances, ensure vessel may be delivered in the space allocated Prepare delivery route, level and compact9.2 BasesPrepare mast base foundationsSurvey, level and shim, mark set out linesAssemble 2 No. mast basesPlace mast bases on foundations, check level, shim as requiredCheck position and alignmentBolt into position9.3 Masts to 36mPre-assemble 12m mast sections (14 total)Fit ladders and platformsClean and lightly lubricate mast point pins and joint holesClean climbing bar location fixing pointsClean bar mounting feet and bar/bar location dowel/holesEnsure bar clamps clean, free from blemishesFit 2 No. 6m 200 sq climbing bars to central fixing points and clamp lightly in position Secure bar for upending mastDeliver mast section c/w bar to Western mast baseLift mast section clear and upend using 2 cranesLift into position and fit mast joint pins, once secure - release craneRepeat process, lifting 2nd mast section onto 1st and securingRepeat process, lifting 3rd mast section onto 2nd and securingRepeat process for Eastern mast base to 3 sections highTemporarily guy masts using Tirfors to concrete blocksCheck alignment of masts and bar / bar spacing and adjust if required9.4 Climbing jacksFit 400T climbing jack c/w articulating ring to each climbing bar at approx foundation EL Level the two jacks to the same elevationDeliver 18m lifting beam and lower into position supported on jacksDeliver and fit 100mm sq pushing bar to lifting beamDeliver and fit 2 No. pump platformsDeliver and locate 2 No. pump unitsHose up to jacks9.5 SuspensionLightly grease assembly location on lift beam for slide bogieDeliver and fit sliding bogie c/w Teflon slide pads & drop link suspension pinDeliver and fit swivel and adapter plate, fit to each other and secureDeliver and fit drop links to swivelLift assembly to height and fit link heads over suspension pin.

The method of preparing the foundation of the mast frame front is as follows:a. 在两根地管（400—CWR615030—17120N—NI及400—CWS615001—17120N—NI）的上方铺设40条200x200x2000mm的枕木。

Lay 40 pieces of crossties of 200x200x2000mm above the two underground pipes (400—CWR615030—17120N—NI及400—CWS615001—17120N—NI)b. 经过平整和压实的地面上铺150mm厚的碎石层。

HDPE管吊装准备工作1.把第一根钢绞线穿于PE管内(在起吊之前进行)因第一根钢绞线带着整根PE管起吊，重量较大，自重垂度亦大，故第一根钢绞线长度较其它各根钢绞线显著增大。

每根钢绞线的下料长度应计算确定。

下料长度L=L0+Ll+L2+L3式中，L0为塔端和梁端锚具夹片之间的距离Ll为梁端锚具夹片外的预留长度L2为塔端锚具夹片外的预留长度L3为第-根钢绞线连同HDPE外套管挂设时由于垂度及预拉力的影响需增加的长度(仅在第一根钢绞线下料时有)。

张拉端锚具夹片外的预留长度除应满足干斤顶张拉要求外，应确保钢绞线张拉后的预留长度满足设计要求。

每根钢绞线外包HDPE皮的剥皮长度也应计算确定。

固定端的剥皮长度应满足:（1)大于(锚具夹片外的预留长度+夹片长度+5cm)；（2)小于(锚具外的预留长度+夹片至锚具端部密封圈之间的距离一5cm)。

钢绞线上未剥皮的长度应满足:(1)大于(上下锚具密封圈之间的距离+固定端剥皮位置至固定端密封圈的距离-上下锚具密封圈之间钢绞线的张拉伸长量+5cm)；(2)小于(上下锚具夹片之间的距离-固定端剥皮位置至固定端夹片之间的距离一上下锚具夹片之间钢绞线的张拉伸长量-5cm)。

张拉端剥皮长度等于(钢绞线下料长度一固定端剥皮长度一钢绞线上未剥皮的长度)。

桥面锚具处的聚乙烯皮应在钢绞线插入索道管和锚具前剥皮。

塔柱处剥皮至预定长度并在用夹子夹住前应去除钢绞线表面油脂，以防打滑。

第一根钢绞线穿人HDPE管内的方法可采用以下三种:（1）用带橡胶轮的牵引机拖动钢绞线（2）用卷扬机拖动钢绞线（3）用人工拖动钢绞线2．连接固定：（1）钢绞线穿过后，起吊PE管前，须用角钢和钢丝绳夹子把钢绞线固定于塔柱端PE管口处，以防滑脱；（2）把膨胀延伸管及其连接钢环滑到塔柱端的外套管上，直至外套管穿过延伸管约15m为止；（3）把哈夫夹具固定到HDPE外套管(标准管)上，螺栓眼向上；（4）用尼龙绳把延伸管和哈夫夹具连接好；（5）用钢绞线夹子夹紧钢绞线，留出包括连接螺栓在内约3OOmm的长度；（6）用U型卡环把塔上5t卷扬机绳头与哈夫夹具中间孔眼连接好；（7）塔内1.5t无级卷扬机钢丝绳通过转向轮伸入锚具下方的专用牵引孔眼内，一旦PE管上端吊至塔外萦道管口时，用1t卷扬机钢丝绳将第一根钢绞线引向塔内锚固。
